Soft Starter Centrifugal Pump Soft Starter Series Type RSWT Optimised algorithm for centrifugal pumps Simple User Interface 3-phase controlled Internally bypassed Multi voltage operation Integrated overload protection (RSWT..V10 models only) Relay Outputs for Alarm/Top of Ramp RSWT40 models: Internally supplied RSWT60 models: 24VAC/DC ( F version) and 100-240VAC ( G version) control/supply options RSWT V10: Auto- or manual reset of alarms Product Description RSWT is a 3-phase controlled soft starter for centrifugal pumps. RSWT controls all the three phases to achieve current balancing on all the phases so as to minimise vibrations during starting and stopping of centrifugal pumps. Through a dedicated self-learning algorithm, the RSWT manages to achieve a very smooth starting and stopping performance of centrifugal pumps with minimal settings resulting in a very easy to use solution. The RSWT up to 25A (11kW @ 400V) comes in a compact 45mm housing thus facilitating replacement of contactors and star/delta starters. The RSWT...V00 version requires just 1 knob setting for the soft-starting/softstopping time of the pump. No further adjustments are required in this case. diagnostic functions including phase sequence, over- and under-voltage monitoring, locked rotor protection and also shorted SCR for improved pump protection in case of abnormal conditions. Soft starter status indication is provided by means of three LEDs (green, yellow, red) for supply, ramping, and alarm indication. Additionally, RSWT (45mm) is also equipped with two output relays for alarm (Normally closed - NC) and top of ramp (Normally - NO) indication. In case of the RSWT V10 series, there is a 4th LED to select whether alarms follow an auto- or manual recovery. In case of manual recovery of alarms, a push button is also available to reset the soft starter from alarm status.

Soft Starter Setting Procedure RSWT...V00 RSWT...V10 1. Ramp-up / Ramp-down 1. Ramp-up 2. Ramp-down 5. Manual/Auto reset of alarms (LED indication) 3. Full load current (FLC) [for overload protection] 4. Test/Reset button The RSWT V00 soft starter series features just 1 knob setting for start/stop time of the pump. Step 1: Set the knob to the desired starting time as required for the specific application. The RSWT will then self-adjust the starting torque at every pump start until an optimum starting torque is achieved. This will take a minimum of 5 starts until the starting parameters stabilise. For more details on how this is done refer to the Mode of Operation section. Note: In this case, the ramp-down will have the same duration of the ramp-up time setting. IMPORTANT: The RSWT knob settings are only checked during IDLE status. Changes in the knob settings during Ramping/Bypass status will only be affected during the following start/ stop. The RSWT V10 soft starter series features 3-knob settings and an additional push button to test the overload protection, reset the alarms and for setting the alarm recovery to Manual or Auto. Step 1: Set the ramp-up time Set the knob to the desired starting time as required for the specific application. Step 2: Set the ramp-down time Set the knob to the desired stopping time as required for the specific application. In this case ramp-down time can be set to a different value from that of the ramp-up time. Note: If no soft-stop is required, set the ramp-down knob from 0 to 1sec. Step 3: Set the full load current (FLC) Adjust the knob setting to the FLC value corresponding to the pump/motor name plate to ensure proper overload protection Step 4: Set the alarm recovery mode Make sure the RSWT is in idle mode (Green LED ) To set the alarm recovery to auto, press the Test/Reset button for a minimum of 5secs. The MANUAL LED (yellow LED) will turn indicating that the alarms will follow an auto-recovery routine. To set the alarm recovery to MANUAL the same procedure as described above applies Note: The RSWT V10 have a default setting of manual alarm recovery (yellow LED MANUAL ) Step 5: Test the overload function To make sure that the overload function is working properly press the TEST/RESET button (during Idle) for about 1sec. The RSWT will trip and the red LED will flash 8 times indicating an overload alarm. The alarm relay (11,12) will also change state to.

Mode of Operation Starting Method The RSWT series of soft starters is based on a current ramp starting methodology to limit the pump starting current and, at the same time minimise water hammering effects. Additionally, the RSWT is equipped with an intelligent and self-learning algorithm to adjust the starting torque automatically at every pump start. The algorithm makes use of the internal current and voltage measurement circuits to detect when the pump starts to rotate. During every start, the RSWT adjusts the starting parameters to achieve a ramp-up time as close as possible to the one set by the user. This function is done automatically by the RSWT and within 5 starts (typically) the proper starting parameters will be found (assuming the load is the same). During ramp-down, the RSWT will use the self-learned parameters to adjust the ramp-down time in such a way to respect the setting done by the user on the ramp-down knob. In the case of the RSWT V00 versions this will be the same as the ramp-up setting. Important: Due to the self-learning algorithm present on the RSWT series, when the RSWT is first tested on a small motor, the starting parameters will be optimised for that motor size. If the same RSWT is then installed/ tested on a larger motor, the starting parameters will be optimised during the first start and the RSWT might trigger an alarm. If this happens, following the alarm recovery period, the RSWT will update the(self-learned) start parameters and perform another start. This process will then continue during successive starts such that the optimal starting parameters are found. Current (Arms) Default star ng current Actual start me (measured by RSWT) Current (Arms) Self-adjustment (1) star ng current Current (Arms) Self-adjustment (n) star ng current User ramp-up se ng Time (sec) User ramp-up se ng Time (sec) User ramp-up se ng Time (sec) Start 1: RSWT starts from default starting voltage/torque (internal) value. The pump start time can be shorter/longer than user ramp-up setting. Start 2: During the 2nd start, the RSWT will start with the self-learned start parameters (from the previous start) to reduce the difference between the user-set ramp-time vs the actual ramp-time measured by the RSWT ( time). Start n: For the nth start, the RSWT algorithm will keep the ramp-time as close as possible to the user set-ramp time. The self-adjusting algorithm will remain active at every start to make sure that the RSWT adapts the starting parameters to any load changes. Note: During motor starting, the RSWT will limit the current to a maximum of 3.5xIe for RSWT...V00 models and 3.5xFLC setting for RSWT.V10 models respectively. 10 Specifications are subject to change without notice (11.06.2014)

Mode of Operation Alarms description The RSWT includes a number of diagnostic and protection features each of which is signalled through a flashing sequence on the red LED. For the RSWT V00 versions, all alarms follow an auto-recovery routine (except for Wrong phase sequence, Shorted SCR and Internal fault alarms) as described in the datasheet. For the RSWT V10 the user can select whether to have an auto-reset or manual reset of of alarms. In auto-reset (auto-recovery) mode, alarms (3,4,5,6,7,8,9 flashes) will recover after a minimum recovery time of 5minutes. In case the same alarm is triggered for 5 consecutive times, then a power supply reset will be required to reset the alarm. Wrong phase sequence (2 flashes) If the connection to the soft starter is not done in the correct sequence (L1, L2, L3), the RSWT soft starter will trigger the wrong phase sequence alarm and the motor will not be started. In such case, user intervention is required to change the wiring sequence as the alarm does not self-recover. Line voltage out of range (3 flashes) 5 sec. 5 sec. At every power-up the RSWT automatically detects the supply voltage level and determines whether it is working on a 220, 400, 480* or 600* V supply. The under- or over- voltage alarm level is then set at a level of -20% and + 20% (from the measured supply voltage level) respectively. If the supply voltage level is out of these limits for more than 5 seconds then the line voltage out of range alarm will be triggered. * Applies to RSWT60 models only. Note: For RSWT60 models over-voltage alarm level (for the case of a 600V supply) is 675V. (600V + 11%) Phase loss (Motor side) (4 flashes) If any of the phases on the load (motor) side becomes open the RSWT will trip after 5seconds to protect the motor from running/starting on 2 phases. Note: This alarm will also be triggered when a current unbalance of >20% is detected on any of the three line currents for a minimum of 5secs. Additionally if a SCR and/or bypass relay is open (damaged) the same alarm will be triggered. Locked rotor (5 flashes) If a current 5xIe for 1sec (for RSWT V00) or 8xFLC setting for 100msec(for RSWT.V10 models) is detected, the RSWT will issue the locked rotor alarm (5flashes). This alarm may indicate a number of different conditions:- 1. The RSWT soft starter rating is small with respect to the load it is controlling 2. Motor windings are damaged 3. Pump with locked rotor Specifications are subject to change without notice (11.06.2014) 11

Mode of Operation Excess ramp-up time (6 flashes) During ramping-up state, if the RSWT detects that the starting current is equal to the maximum starting current allowed (3.5xIe for RSWT..V00 or 3.5xFLC setting for RSWT..V10 models) for 80% of the ramp-up time setting, the RSWT will trigger this alarm. Over-temperature (7 flashes) The RSWT soft starter constantly measures the heatsink and thyristors (SCRs) temperature. If the maximum internal temperature is exceeded (for a minimum of 0.5sec) an over-temperature alarm is triggered and the RSWT will enter into a selfrecovery mode to allow the soft starter to cool down. This condition can be triggered by too many starts per hour, an overload condition during starting and/or stopping or a high surrounding temperature. Overload (8 flashes) Before going into bypass state, the RSWT will check if the measured current is > Imax bypass. If this condition is detected, the alarm will be triggered. If during bypass state, the measured current by RSWT is > Imax bypass for a minimum of 5sec the alarm will be triggered. RSWT..V10 models: The RSWT has built-in thermal model motor overload protection. The motor current is continuously monitored and the expected temperature is calculated based on this monitored current. The RSWT is equipped with a virtual motor model to estimate the motor windings temperature. Depending on the level of overload, determined through the internal current measurement, RSWT will trigger the overload alarm based on a certain delay in accordance with overload trip class 10 characteristics. Note: I max bypass=1.05 x Ie Overload Trip Curves 10000s 1000s 100s Time to trip 10s HOT COLD 1s 0.1s 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 6.0 6.5 7.0 7.5 8.0 Times FLC Supply voltage unbalance (9 flashes) The unit measures the voltages on all the three phases and if there is a difference of more than 20% for >=5sec between any of the phases, the RSWT triggers the voltage unbalance alarm to prevent motor damage. Shorted SCR (10 flashes) In case the RSWT detects that there is a damaged (shorted) thyristor (SCR) on any of the three phases, the soft starter will trip. Note: this alarm is not resettable and it is suggested to replace the unit and contact a Carlo Gavazzi representative should this alarm occur. Internal fault (Red LED continuously ) In the case there is an internal fault in the RSWT circuitry, the Red LED will remain continuously. Note: This alarm is not resettable and it is suggested to replace the unit and contact a CG representative should this alarm occur. 12 Specifications are subject to change without notice (11.06.2014)
